DETAILED DESCRIPTION

The disclosed augmented reality head gesture recognition systems willbecome better understood through a review of the following detaileddescription in conjunction with the figures. The detailed descriptionand figures provide merely examples of the various embodiments describedherein. Those skilled in the art will understand that the disclosedexamples may be varied, modified, and altered and not depart from thescope of the embodiments described herein. Many variations arecontemplated for different applications and design considerations;however, for the sake of brevity, the contemplated variations may not beindividually described in the following detailed description.

Throughout the following detailed description, examples of variousaugmented reality head gesture recognition systems are provided. Relatedfeatures in the examples may be identical, similar, or dissimilar indifferent examples. For the sake of brevity, related features will notbe redundantly explained in multiple examples. Instead, the use ofrelated feature names will cue the reader that the feature with arelated feature name may be similar to the related feature in an exampleexplained previously. Features specific to a given example will bedescribed in that particular example. The reader is to understand that agiven feature need not be the same or similar to the specific portrayalof a related feature in any given figure or example.

Individuals that work in industries where their hands must remain freeto perform tasks may use wearable computer systems to retrieve and/orview information needed to perform the tasks. For example, individualsworking in manufacturing facilities may be required to maintain a cleanand hygienic manufacturing area to prevent cross-contamination.Additionally, in the manufacturing environment and other environments,it may be required to record that all the steps and instructions in adefined manufacture procedure were performed. Wearable computer systemsmay aid in recording all the steps and instructions that were performedand investigating or documenting deviations taken during themanufacturing procedure. The records of the manufacturing anddistribution of items with a complete manufacturing history may enable amanufacturer to retain the manufacturing information in a comprehensibleand accessible format in case an investigation is needed to determine aproduct defect or failure. In another example, in retail operationenvironments, sales assistants or inventory control clerks may usewearable computer systems to identify products and/or retrieve productinformation associated with the product.

It may be difficult for individuals to interact with conventionalwearable computer systems. For example, in the clean and hygienicmanufacturing conditions, an individual may not be able to use theirhands to interact with the wearable computer systems in order tomaintain the clean and hygienic environment. Similarly, in a medicalenvironment, medical personnel may not be able to use their hands tointeract with the wearable computer systems in order to avoidintroducing contagions into an operating environment. The conventionalwearable computer systems may use touch-screens or mobile devices forthe users to interact with the system.

Additionally, the conventional systems may use integrated displays orremote displays to display information to the individuals. However, theconventional integrated displays or remote displays may not be viewableto the user. For example, medical personnel may not be able to view theconventional integrated displays or remote displays as they performmedical procedures. Similarly, an individual in a clean and hygienicenvironment performing a manufacturing process may not be able to viewthe conventional integrated displays or remote displays as they performmanufacturing procedures.

Implementations of the disclosure address the above-mentioneddeficiencies and other deficiencies by providing methods, systems,devices, or apparatus to display an augmented reality environment tousers and provide interactive user interfaces. In one embodiment, theaugmented reality systems may be head-mounted systems. The augmentedreality systems may include sensors and/or detector units to detect,gather, and/or transmit data to a processing device. The processingdevice may be an integrated or onboard processing device or an externalor remote processing device. The augmented reality systems may includean augmented reality display to overlay or display information to auser.

In one embodiment, the augmented reality systems may provide a useraccess to remote help, capture images, take sensor measurements, senddata to send to a remote individual, and so forth. For example, anaugmented reality system may transmit a still image or a video from aperspective of the user, also referred to as a “see what I see”perspective. In another example, the augmented reality systems mayoverlay images or information into an augmented reality environmentdisplay for a viewer to see a projected perspective of the images orinformation. An advantage of the augmented reality system may be toprovide a user interface for a user to interact with in a variety ofenvironments, include hands-free environments, clean and hygienicenvironments, collaborative environments, remote environments, and soforth.

The processing device 116 may be configured toexecute computer-executable instructions and control the electronicelements of the wearable device 100.

The processing device 116 may acquire data from other elements of thewearable device 100 or from external sources and execute computerexecutable code in response to this data. For example, the processingdevice 116 may be configured to acquire data from the motion capturedevice 124 such as data that corresponds to a user gesture. Theprocessing device 116 may additionally or alternatively acquire datafrom the microphone 122. In some examples, the processing device 116 mayacquire data from a separate device, such as a portable music player, apersonal data assistant (PDA), a smartphone, a global positioning system(GPS), or the like.

The processing device 116 may be in coupled to the first image generator118 and/or the second image generator 120 and may instruct the firstimage generator 118 and/or the second image generator 120 to generateand manipulate a display projected on lens 104. In one example, theprocessing device 116 may generate a user interface on the lens 104. Theprocessing device 116 may acquire data from other elements or sensors ofthe wearable device 100 and manipulate the user interface in response tothis data.

The first image generator 118 and/or the second image generator 120 maybe attached to the first temple 110 and may be substantially alignedwith the lens 104. The wearable device 100 may include additional imagegenerators to augment the expanse of generated images over the lens 104surface area. The first image generator 118 and/or the second imagegenerator 120 may be configured to display images on the lens 104 facingan eye or eyes of the user 102 in FIG. 1A in response to instructionsexecuted by the processing device 116. These images often may overlayand/or augment a naturally viewed scene within a field of vision of theuser 102. The first image generator 118 and/or the second imagegenerator 120 may display opaque and/or partially transparent images onthe lens 104.

The motion capture device 124 may be connected to the bar 114. In oneembodiment, the motion capture device 124 may be oriented away from theuser 102 when the user 102 is wearing the wearable device 100 to captureimages and motion occurring beyond the lens 104. In another embodiment,the motion capture device 124 may include an image sensor 126 with acamera, a light source 128, and a depth sensor 130. The motion capturedevice 124 may capture images that include at least a portion of theenvironment surrounding the wearable device 100 (such as a head-mounteddevice or a head-mounted display).

The image sensor 126 may be connected to the bar 114. In one embodiment,the image sensor 126 may be oriented away from the user 102 as the user102 wears the wearable device 100. The image sensor 126 may beconfigured to capture an image from a scene and communicate datacorresponding to the captured image to the processing device 116. Theimage sensor 126 may capture light within the visual spectrum and/orlight outside the visual spectrum. For example, the image sensor 126 maycapture infrared or ultraviolet light.

The light source 128 may be connected to the bar 114. The light source128 may be substantially aligned with the image sensor 126. The lightsource 128 may be configured to project light in a defined direction.This light is reflected from an object and may be captured by the motioncapture device 124. The reflected light may allow the motion capturedevice 124 to more accurately capture images and motion of objects orthe surrounding environment. The light source 128 may project visuallight and/or light outside the visual spectrum.

The depth sensor 130 may be connected to the bar 114. The depth sensor130 may be configured to capture images and motion from a scene at adifferent angle than image sensor 126. The data captured from thissecond viewpoint may allow the processing device 116 to compare the datareceived from the depth sensor 130 to the data received from the imagesensor 126 to better detect a depth of objects in the environmentsurrounding the wearable device 100.

FIG. 2 illustrates an augmented reality system 200 with a user 102wearing the wearable device 100, according to an embodiment.

In another embodiment, an alignmentsensor may measure a difference between a position of the user 102indicated by the position sensor and the actual location of the user'seyes and generates a view aligned to the user's line of sight. In oneembodiment, the lens 104 in FIGS. 1A and 1B may project a virtual oraugmented reality environment or a virtual or augmented reality object208 at a set focal distance from the user 102. In one example, the focaldistance may be along the second plane 206. The virtual or augmentedreality environment or the virtual or augmented reality object 208 maybe a user interface that enhances or supplements the user's interactionsin the physical environment and/or physical objects approximate orsurrounding the user.

FIG. 3 illustrates a system 300 of the wearable device 100 in FIGS.1A-2, according to an embodiment. The system 300 may include a detector302, sensors 304, a transceiver 306, an augmented reality display 308, alocal processing device 310, a remote processing device 312, and anoptimizer 314.

In another embodiment, the localprocessing device 310 may be a local processing device attached to orintegrated into the wearable device 100.

The local processing device 310 may be positioned proximate to the userthat interacts with a remote processing device 312. In anotherembodiment, the remote processing device 312 may be a remote processingdevice that may be external to the wearable device 100. The transceiver306 may receive instructions from the local processing device 310 toproject the augmented display 20. The transceiver 306 may measurecharacteristics from the physical environment and communicate the datato the local processing device 310 and an optimizer 314.

The optimizer 314 may be in communication with the remote processingdevice 312, the local processing device 310, and the transceiver 306.The transceiver 306 may measure or detect user characteristics orgestures including head position, movement, speed, etc. In one example,using gestures, the user may open applications to be displayed in theaugmented environment. These applications may include task flows,attached documents, and so forth. The gestures may allow the user toaccess the applications and execute instructions such as selectinstructions, open instructions, scrolling instructions, movementinstructions, and so forth. Alternatively, the gestures may be usedoperate on the icon representing the application by changing the size(zooming in and out), color, sound, and so forth. The gestures mayinclude the user performing scrolling gestures, tapping gestures, orclicking gestures with respect to a virtual object. The scrollinggestures may include body motions, head motions, hand motions, and soforth.

FIG. 4A illustrates a gesture 402 detected by a sensor of the wearabledevice 100, according to an embodiment. Some of the features in FIG. 4Aare the same or similar to some of the features in FIGS. 1A-3 as notedby same reference numbers, unless expressly described otherwise. Asdiscussed above, the wearable device 100 may include one or more sensorsto detect a gesture or a movement of a user 102 wearing the wearabledevice 100. In one example, the sensor may be a gyroscope, a motionsensor, an accelerometer, a three-dimensional (3D) accelerometer, and soforth. In one example, the wearable device 100 may include multiplesensors. In one embodiment, the wearable device 100 may include a sensorto determine the orientation of a head 404 and/or the acceleration ofthe head 404. The sensor may be a gyroscope, an accelerometer, a 3Daccelerometer, and so forth. For example, the wearable device 100 may bea head-mounted display with an integrated gyroscope or accelerometerthat may sense different orientations of the head 404 and senseaccelerating movements of the head 404.

The wearable device 100 may use the sensor to detect and identify thedifferent movements of the head 404. For example, the wearable device100 may use data from the sensor to detect a left head movement. In oneembodiment, the wearable device 100 may associate the left head movementwith an instruction from an input device. For example, the wearabledevice 100 may associate the left head movement with a left or rightswipe or a left or right scrolling of a finger on a touch sensor or atouch screen device.

FIG. 4B illustrates a gesture 406 detected by a sensor of the wearabledevice 100, according to an embodiment. Some of the features in FIG. 4Bare the same or similar to some of the features in FIGS. 1A-4A as notedby same reference numbers, unless expressly described otherwise. Asdiscussed above, the wearable device 100 may include one or more sensorsto detect a gesture or movement of the head 404 wearing the wearabledevice 100. In one example, the wearable device 100 may use data fromthe sensor to detect a right head movement. In one embodiment, thewearable device 100 may associate the right head movement with aninstruction from an input device. For example, the wearable device 100may associate the right head movement with a right or left swipe or aleft or right scrolling of a finger on a touch sensor or touch screendevice.

FIG. 4C illustrates a gesture 408 detected by a sensor of the wearabledevice 100, according to an embodiment. Some of the features in FIG. 4Care the same or similar to some of the features in FIGS. 1A-4B as notedby same reference numbers, unless expressly described otherwise. Asdiscussed above, the wearable device 100 may include one or more sensorsto detect a gesture or movement of the user 102 wearing the wearabledevice 100. In one example, the wearable device 100 may use data fromthe sensor to detect an upward and/or downward movement of the head 404.In one embodiment, the wearable device 100 may associate the upwardand/or downward head movement with an instruction from an input device.For example, the wearable device 100 may associate a upward headmovement with an upward scrolling movement of a finger on a touch sensoror touch screen device and a downward head movement with an downwardscrolling movement of a finger on a touch sensor or touch screen device,or vise versa.

In one embodiment, the sensor(s) of wearable device 100, such as agyroscope, may identify an initial orientation of the head 404. In oneexample, the initial orientation of the head 404 may be an orientationof the head 404 when a scrolling session is initiated for a selectedapplication or function. In this example, when a user initiates ascrolling session the wearable device 100 may use the sensor(s) todetermine an orientation of the head at the initiation of the scrollingsession and define that orientation as initial or default orientation.In another example, when the scrolling session initiates, the wearabledevice 100 may provide a prompt or a notification to the user toposition their head at a default or user defined orientation to set theinitial orientation. In another example, the user may perform a gestureor provide an input via an input device to reset the initial orientationto a new default or initial orientation used to control movement and/orscrolling functions or instructions as discussed herein.

A processing device of the wearable device 100 may determine a locationwithin a user interface that the user is viewing or is focusing on. Forexample, the processing device may identify a location on a page in adocument displayed in the user interface that the user is viewing. Inone embodiment, to determine the location in the user interface that theuser is viewing or focusing on, the wearable device 100 may include oneor more optical sensors to determine an orientation and/or position ofthe eye or retinas of the user relative to the user interface. Asdiscussed above, the wearable device 100 may include a transceiver. Inanother embodiment, the transceiver may be positioned proximate to theuser's line of sight and the processing device may approximate alocation the user is viewing within the augmented reality environmentbased on where the transceiver is directed in the augmented realityenvironment.

In another embodiment, to determine the location in the user interfacethat the user is viewing or focusing on, the wearable device 100 may usea sensor to detect a gesture indicating a body part of the user (such astheir hand) is hover over or approximate an element displayed in theuser interface. In another embodiment, to determine the location in theuser interface that the user is viewing or focusing on, the wearabledevice 100 may use a sensor to perform gaze tracking of the user. Whenthe wearable device 100 has determined location within a user interfacethat the user is viewing or is focusing on, the wearable device 100 maytarget or lock onto the element or object in the user interface at thatlocation and perform a movement function or a scrolling function basedon a movement or position of the user's head, as described herein. Inone example, when the element or object has been identified by theprocessing device of the wearable device 100 the movement or scrollingfunction may only be applied to the selected element or object and otherelements or objects displayed in the user interface may not change whilethe movement function or the scrolling function is performed. When theuser has completed the movement function or the scrolling function for aselected object or element, the user may perform a different gesture toindicate the completion of the movement function or the scrollingfunction and/or may select another object or element for moving orscrolling as described herein.

In one embodiment, a display device of the wearable device 100 maydisplay a virtual object as an image within the augmented realitydisplay. After determining a location in the augmented realityenvironment that the user is viewing, the processing device may executemovement or scrolling instructions or other instructions associatedbased on gesture with respect to the virtual object the user is viewing.The motion of the user's head 404 may correspond to the movement orscrolling of the virtual object. In another embodiment, the locationsensor may adjust for the difference between the position of thetransceiver and the user's vision and display the virtual object(s) tobe aligned to the user's line of sight.

Regarding FIGS. 4A-4C, in one embodiment, a head 404 of user 102 may bepositioned along an x-axis, a y-axis, and a z-axis. The gestures may bein along a plane of a body or head 404 of the user 102. For example, thehead 404 of the user 102 may act as a joystick controller. In oneembodiment, an initial orientation of the head 404 may be a start of thegesture. The initial orientation may be a default orientation for agesture. In one example, when the head 404 moves past the initial tilt,the scrolling speed corresponds to the range of the head motion. Forexample, when the user tilts their head 404 at a first angle or range ofangles (such as an angle or range between 0.1 to 5 degrees) from theinitial orientation, the scrolling function may scroll in the directionof the head tilt at a first speed. In another example, when the usertilts their head 404 at a second angle or range of angles (such as anangle or range between 5.1 to 10 degrees) from the initial orientation,the scrolling function, au scroll in the direction of the head tilt at asecond speed. In another example, as the angle or range of anglesincreases the scrolling speed may correspondingly increase. When thehead 404 returns to the original position, the scrolling may stop.

In another embodiment, the wearable device 100 may follow the head 404and the scrolling associated with the head gestures may remain constantas the head 404 remains at the same tilt level until the head 404returns back to the initial position. In another embodiment, onlyselected or locked elements in a display or a program may be scrolledwhile the head 404 is moving rotationally and/or translationally.

As discussed below, FIGS. 4A-C illustrate movements or gestures detectedby a sensor, such as a gyroscope. The arrows indicate the movement ofthe head. FIG. 4A may illustrate a left head rotational motion may beassociated with a right swipe command or a right scrolling command andFIG. 4B may illustrate a right rotational motion may be associated witha left swipe command or a left scrolling command, or vise versa. FIG. 4Cmay illustrate an up or down nodding motion associated with a upward ordownward scrolling command. The acceleration detected by theaccelerometer indicates a speed and/or acceleration of the headmovement, which may correspond to a magnitude of the scrolling.

The gestures 402, 406, and/or 408 discussed above are not intended to belimiting. While head movement gestures may be discussed, othermovements, such as body motions or hand motions may be associated withinstructions executed by the processing device.

FIG. 5 is a flowchart 500 for a method to move or scroll a virtualobject, according to an embodiment. The method may include identifying afirst gesture for selecting a virtual object for a movement command(block 502). In one example, the first gesture may be a hoveringgesture, a hand motion, a finger tapping motion, and so forth. Inanother example, the first gesture may be a hand motion with a fingerlingering on the virtual object for a predetermined time. In anotherexample, when the movement command has not been initiated, the headmotion of the user may be used to control a cursor within the userinterface and once a target in the user interface (such as an object orelement) has been selected or identified in the user interface, theprocessing device may switch to the movement command for the selected oridentified target corresponding to the head motion.

The method may include displaying an indicator showing the virtualobject being selected, such as being hovered over (block 504). Forexample, a cursor may be used to select the virtual object and once theelement is selected, the cursor may be changed to be an indicatorassociated with the movement command. In once example, the indicator maybe indicia, text, a graphical object (such as an arrow), or anothervisual indicator. In another embodiment, the indicator may includechanging a color and/or an illumination intensity of the user interface,a portion of the user interface, or the virtual object. In anotherembodiment, the indicator may include outlining the selected element orobject in the user interface.

The method may include the processing device selecting the virtualobject for the movement command by performing a second gesture, such asa user moving their head away from an axis relative to the user (block506). In one example, the user may rotate the head along the axis (alsoreferred to as a head axis). In another example, when the user tiltshis/her head beyond a threshold point or angle relative to the axis, aprocessing device may use a sensor to automatically recognize themovement function and identify the virtual object the user selected whenthe user first tilted his/her head to automatically execute the movementcommand for that virtual object. In another embodiment, the user mayconfirm the selection with a command, e.g. a head gesture or an audibletone.

The method may include the processing device tracking a change inlocation of the selected virtual object (block 508). For example, thevirtual object may move within an augmented reality environment as theuser moves with the augmented reality environment and the processingdevice may track a location of the selected virtual object as it moveswithin the augmented reality environment. The method includes performingthe movement function for the virtual object (such as scrolling ormoving the selected virtual object) when a tilting of the head passes athreshold tilting level (block 510). In another embodiment, the movementcommand may include a scrolling function to scroll text and/or graphicsof the virtual object up, down, or across. In another embodiment, themovement command may include a movement function to move the entirevirtual object from a first location to a second location within theaugmented reality environment.

In one embodiment, the wearable device may move with the user's head. Asdiscussed above, the method may include selecting or locking onto thevirtual object. In another embodiment, when the user's head rotatespassed the threshold, the processing device may start to scroll or movethe virtual object. For example, the user may unconsciously orunintentionally move their head a minor amount in performing other tasksor due to a normal physiological movement of the body. In this example,the processing device of the wearable device may define a referencerotational axis corresponds to an axis coincident with the head as adefault axis from which to measure a relative movement of the head. Theprocessing device may then define a threshold distance that the headmust move relative to the reference rotational axis before a scrollingfunction may be performed. In one example, the threshold distance may bea predefined distance or angle from the reference rotational axis, suchas 3 degrees.

In another example, the processing device may monitor the movement ofthe head of the user over a period of time to identify the unconsciousor unintentional movements of the user's head and filter out theidentified unconscious or unintentional movements of the user's head. Inanother embodiment, the processing device may filter out movements ofthe user's head that exceed a speed threshold or that have an erratic orirregular pattern. For example, when the user moves their headrelatively quickly such that the movement exceeds a defined speed(linear speed, angular speed, and/or rotational speed), the user may notintend to scroll with the head movement and may be moving their head toavoid an object, moving their head due to an involuntary twitch, may beturning their head to talk with someone, and so forth. Such movementsmay be filtered out by the processing device of the wearable device.

The method may include, the processing device ceasing the movementcommand when the user's head is returned to an original position (block512). The method may include, the processing device exiting a movementcommand mode when a new gesture sequence is not detected (block 514).For example, when the processing device does not receive a gesture ormovement instruction or input for a threshold period of time, theprocessing device may exit the movement command mode. Not receiving thegesture instruction or input for the threshold period of time mayindicate that the user in no longer interacting with the interface,using the movement command mode, or that the user has become inactive.In this example, the processing device may automatically exit themovement command mode so that user may perform other activities, theprocessing device may shutdown, or the processing device may enter asleep mode.
